不同原料对锂离子电池正极材料LiCoO2的结构和性能的影响

摘要

在空气气氛下,采用高温固相法,用不同的锂源(Li2CO3、LiOH·H2O)和钴源(自制的β-Co(OH)2、CoOOH)分别合成了LiCoO2样品,通过XRD和电化学性能测试等方法,研究了不同原料对锂离子电池正极材料LiCoO2的结构和电化学性能的影响.结果表明:以LiOH·H2O为锂源,CoOOH为钴源,制备出的锂离子电池正极材料LiCoO2,其结构和电化学性能均较好.%In air, LiCoO2 was synthesized by high solid state reaction with different raws of Li and and electro-chemical properties, the effect of different raws on structure and properties of lithium ion bat-tery positive material LiCoO2 was discussed. The results showed that LiCoO2 synthesized with LiOH·H2O and CoOOH revealed better structure and electro-chemical properties.
